Yeah but that may mean that you might have been simply riding too short bikes or too narrow bikes before. So it's more a matter of sizing. If you are comfortable then it's gucci. I'd just make sure to note if you feel any changes in riding performance (crashes, insecurity on steep or flat terrain etc). Tbh I was more making a comment about the general trend in our community where people take some trends to the extreme. I've seen tiny kids on 820mm bars. Hell I've even got bitten by renting out a too long bike when looking for the right fit and only realized when our guide told me I am riding weird and not shifting my weight back on really steep terrain ( I was literally unable to do so, crashed an abnormal amount of times that day too)Like anything else there's such thing as too long of a bike or too wide of a bar. You can also do this super amazing thing called moving your hands in and out depending on what you're riding. Obviously if your bars are so wide that you don't have the range of motion to fully lean the bike over you have a problem, but the 10mm per side past 780mm hasn't been an issue for me; the fact that I have a fairly long wingspan for my height may have something to do with it - YMMV.
